Method Detail

countRoot

T countRoot(String rootResourceType)

The root query (select statement) for a count query

Parameters:

rootResourceType -

Returns:

dataRoot

T dataRoot(String rootResourceType)

The root query (select statement) for the data query

Parameters:

rootResourceType -

Returns:

joinResources

T joinResources(T queryData)

Finish the data query by wrapping the root and joining the resources table

Parameters:

queryData -

Returns:

getParameterBaseQuery

T getParameterBaseQuery(T queryData)

Get the join to which we want to attach all the parameter tables. This makes it easier to build different styles of joins

Parameters:

queryData -

Returns:

includeRoot

T includeRoot(String rootResourceType)

The root query (select statement) for the include query. This query is different than the data root because of the need to support version references for _include searches. For this, we join: xx_RESOURCES.LOGICAL_RESOURCE_ID = xx_LOGICAL_RESOURCES.LOGICAL_RESOURCE_ID and allow the filter to specify the version_id constraint. However, we still need to assert that the resource has not been deleted, so we keep: xx_LOGICAL_RESOURCES.IS_DELETED = 'N'

Parameters:

rootResourceType -

Returns:

wrapInclude

T wrapInclude(T query)

Parameters:

query -

Returns:

sortRoot

T sortRoot(String rootResourceType)

The root of the FHIR search sort query

Parameters:

rootResourceType -

Returns:
